Meth and the Brain. 1  Meth releases a surge of dopamine, causing an intense rush of pleasure or prolonged sense of euphoria. 2  Over time, meth destroys dopamine receptors, making it impossible to feel pleasure. 3  Although these pleasure centers can heal over time, research suggests that damage to users' cognitive abilities may be permanent.
Ammolite is an opal-like organic gemstone found primarily along the eastern slopes of the Rocky Mountains of North America. It is made of the fossilized shells of ammonites, which in turn are composed primarily of aragonite, the same mineral contained in nacre, with a microstructure inherited from the shell.
Ammolite is a trade name given to a thin iridescent aragonite shell material that is found on two species of extinct ammonite fossils (Placenticeras meeki and Placenticeras intercalare). Other less-frequently used trade names for Ammolite are Calcenite and Korite. It is also known simply as ammonite shell. Ammolite is a rare material.
